What year is your car and what is the mileage and where do you live? I believe due to condensation water gets inside the housing over time to some degree.
Traction control was on. It's an AWD so I want the grab. I usually have it in eco but at that time I paddle shifter and had it in sport which I only use when paddle shifting every once in a while when I miss manual and RWD.
Not sure if this is transmission fluid related after seeing that picture of the valvebody.

But yeah if TC was on and it bounced, that's interesting.

OP the first thing would be to reset the ECM. Easy way is to pull the negative battery cable for 10 min but you'll have to reset the windows and all that jazz.
You could also turn the ignition to run mode but DO NOT start the engine (leave foot off the brake).
With the key on evenly depress the throttle to the floor completely and then let up at the same even controlled rate.
Repeat 3 times.
Turn the key off.
Go drive the vehicle and report back.
Its a Throttle By Wire TBW issue. That simple step above has worked on many makes and models. Give it shot.

I tried the simple step above ( run mode and depress the throttle), and it's been running smooth as butter. It's only been a day, so I'll give an update if anything acts up again. When I told the dealer this, he agreed that it was a drive by wire issue. Thanks for your input. I've learned that most times the simplest explanation/solution is the best.
